MUSIC-LEAF TURNER.

Specification of Letters Patent. i

Patented Dec. 5, 1905.

Application filed March 29, 1905. Serial No. 252,653.

T at whom it may concern.-

Be it known that we,RAPHAEL O. GALLINANT, a resident of Ridgefield Park,in the county of Bergen and State of New Jersey, and Jothe following isa full, clear, and exact description.

This invention relates to improvements in devices for turning the leavesof bound music, the object being to provide a leaf-turner of simple andinexpensive construction and which may be conveniently operated by amusician without removing his hands from the instrument on which he maybe playing.

We will describe a music-leaf turner embodying our invention and thenpoint out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of a music-leaf turner embodying ourinvention. Fig. 2 is an elevation, partly in section, of the upperportion thereof. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4is a section on the line 4 4 of Fig. 2. Fig. 5 is a section on the line5 5 of Fig. 2, and Fig. 6 is a fragmentary view showing a modification.

The standard of the device comprises tubular telescoping members 10 11,the member 11 being held as adjusted by means of a setscrewfl2, andattached to the lower section 10 are the swinging legs 13. Extendedupward from the upper standard member 11 and adapted for engagement withbound music are spring yielding arms 14 15, the upper ends of which arecurved inward, as indicated at 16, to form clamping-bars, while at thelower portion the music is engaged by springfingers 16, attached to saidmembers 14 and 15.

Mounted to swing on the stem portion 17 of the standard are arms 18,which arms have a spring-clip 19 at their ends for engaging with amusic-sheet. Also mounted to swing on the stem portion 17, forward ofthe arms 18, is a shifting device for the arms 18, comprising a member20, having a spring yielding finger 21 for engaging with the flangeportion 22 of the arms 18. It will be noted that the flange portions 22are inclined downward and outward, so that the finger 21 will engagewith said flange portions during a partial rotary movement around thestem 17, and then the finger 21, moving on an arc of a smaller circle,will pass outward from the end of the flanges. The object in making theflange 22 inclined is because the necessary inaccuracies of workingmight cause the finger 21'to be farther from the arm 18 at some positionof its revolution than at-the start. If the apparatus is so adjustedthat the finger 21 is sure to engage the flange 22 at the beginning ofthe motion, then the inclination of the flange 22 will insure theengagement between the finger 21 and the flange 22 until the finger 21passes outside the flange 22.

Attached to the member is a bevel-pinion 23, meshing with a bevelgear24, the said bevel-gear 24 being mounted on a stud 25, attached to thestem 17, and arranged within the gear 24 is a spring 26, one end ofwhich is attached to the gear-wheel, the other end being attached to thestud 25.

Extended outward from the gear 24 is an arm 27, attached to which is achain 28, the said chain passing through a lateral opening 29 in theupper member 11 of the standardand thence downward through the twomembers of the standard, connecting with a foot plate 30. As clearlyshown in Fig. 4 the chain 28 passes over a pulley 31, placed adjacent tothe opening 29.

In the operation a downward pressure on the foot-plate 30 will rotatethe gear-wheel 24, and consequently impart a rotary movement to themember 20, so that the arm 18 engaged thereby will swing the sheet ofthe music to which it is connected. As before stated, the

spring-pressed member 21 will pass outward from the end of the flange22, and then upon releasing the pressure on the plate 30 the spring 26will return the member 20 to the right, so that the finger 21 will passunder the flange 22 of the arm engaging with the next sheet of music.

In Fig. 6 we have shown a device for holding or engaging with a singlesheet of music. This device consists of a horizontal arm 32,- having aclip 33 at its end for engaging with the music-sheet, and a vertical arm34, having a clip 35 for engaging with the inner edge of themusic-sheet. Said arm is also provided with a flange portion 22.

Having thus described our invention, we claim as new and desire'tosecure by Letters Patent 1. A music-leaf turner comprising an armmounted to swing, a flange on said arm, the said flange being downwardlyand outwardly inclined a gear-actuated swinging member, and aspring-pressed member on said member for engaging with said flange.

2. A music-leaf turner comprising a standard, an arm mounted to swing onsaid standard, an inclined flange on said arm, a gearactuated swingingmember on the standard, and a spring-pressed member on said member forengaging with said flange.

3. A music-leaf turner comprising a tubular standard a plurality of armshaving swinging connection with the standard-flanges on said arms, thesaid flanges being inclined downward and outward a spring-pressed lingeron said member for engaging with the flanges of said arms, a pinion onsaid member, a gearwheel mounted on the standard and meshing with saidpinion on the standard, afoot-actuated mechanism for moving saidgear-wheel in one direction, and comprisinga chain passing through thetubular standard, and a spring for moving the gear-wheel in the oppositedirection.

4. A music-leaf turner comprising a standard,arms extended upward fromsaid standard, spring-clips arranged in said arms, the upper ends ofsaid arms being curved inward sheetengaging arms having rotaryconnection with the standard, and means for causing the rotarymovements.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
